What is a pulley sleeve? A pulley sleeve wrench should be a ratchet quick wrench (quick lock du wrench), which is a manual screw tightening tool equipped with many specifications of socket heads and irregular extension rods, making it convenient and fast. It also has a switch to change the direction of rotation, which can be tightened or loosened.

There is also a single head, double head, and multi specification adjustable handle ratchet ring wrench (with fixed holes). It is connected by the main and secondary plum blossom sleeves of different specifications and sizes by interlocking the female and male keys of the hinge key. Due to the fact that a plum blossom sleeve has two specifications of plum blossom shaped through holes, it can be used for tightening screws of two specifications, thereby expanding the scope of use and saving raw materials and labor costs.

The movable wrench handle of marine diesel engine accessories can easily adjust the angle of wrench use. This wrench is used for tightening screws and has the characteristics of strong applicability and convenient use.
